Long-tailed macaques are found in primary, secondary, coastal,
mangrove, swamp, and riverine forests in Southern Indochina,
Burma, Indonesia, Philippines, and India's Nicobar Islands.
Because the monkeys are tolerant of humans, they may be found
near villages.
These monkeys sport gray to reddish brown body hair, which
is lighter on their undersides. The hair on the crown of the
head grows into a pointed crest. Male long-tailed macaques have
whiskers and mustaches; females have beards. While males grow
to between 16 and 25 inches tall, females only reach an average
height of 15 to 19 inches. Males weigh approximately 10 to 18
pounds and females 5 to 12 pounds.
Long-tailed macaques live in groups of 10 to 48 individuals.
In these groups, there are generally 2.5 females for each male.
All juvenile males leave the group by age seven.
Females reach sexual maturity at 4 to 4.5 years, males at 4
years. Females give birth approximately every 13 months, having
a gestation period of between 5 and 6 months. Their average
lifespan is 37.1 years.
Sixty-four percent of the long-tailed macaque's diet
consists of fruit. Seeds, buds, leaves, other plant parts, and
animals such as insects, frogs, and crabs make up the rest.
